You can only stop someone following you by blocking them – you cannot choose who likes your page, unlike adding members to a group or accepting or declining friend requests.
you can share on a wall, like your profile, but based on Facebook’s algorithm, you will be shown to a set amount of your followers.
Your profile is where you should network personally. You can join groups, like or follow pages, and accept friend requests or be followed.
